Each of the aforementioned features of the optical image capturing lens assembly can be utilized in various combinations for achieving the corresponding effects.

According to the optical image capturing lens assembly of the present disclosure, the lens elements thereof can be made of glass or plastic materials. When the lens elements are made of glass materials, the distribution of the refractive power of the optical image capturing lens assembly may be more flexible to design. The glass lens element can either be made by grinding or molding. When the lens elements are made of plastic materials, manufacturing costs can be effectively reduced. Furthermore, surfaces of each lens element can be arranged to be aspheric (ASP), since the aspheric surface of the lens element is easy to form a shape other than a spherical surface so as to have more controllable variables for eliminating aberrations thereof, and to further decrease the required amount of lens elements in the optical image capturing lens assembly. Therefore, the total track length of the optical image capturing lens assembly can also be reduced. The aspheric surfaces may be formed by a plastic injection molding method, a glass molding method or other manufacturing methods.

According to the optical image capturing lens assembly of the present disclosure, additives can be selectively added into any one (or more) material of the lens elements so as to change the transmittance of the lens element in a particular wavelength range. Therefore, the stray light and chromatic aberration can be reduced. For example, the additives can have the absorption ability for lights in a wavelength range of 600 nm-800 nm in the optical image capturing lens assembly so as to reduce extra red light or infrared lights, or the additives can have the absorption ability for lights in a wavelength range of 350 nm-450 nm in the optical image capturing lens assembly so as to reduce blue light or ultraviolet lights. Therefore, additives can prevent the image from interfering by lights in a particular wavelength range. Furthermore, the additives can be homogeneously mixed with the plastic material, and the lens elements can be made by the injection molding method. Moreover, the additives can be coated on the lens surfaces to provide the aforementioned effects.

The optical properties of the aforementioned image correcting element, such as curvature, thickness, refractive index, position, surface shape (convex or concave, spherical or aspheric, diffraction surface and Fresnel surface, etc.) can be adjusted corresponding to the demands of the imaging apparatus. Generally, a preferred configuration of the image correcting element is to dispose a thin plan-concave element having a concave surface toward the object side on the position closed to the image surface.
